So saw a couple things I wanted to chime in on here.
First of all: I want one. Can't wait. NOW PLEASE!
Second someone mentioned: "No way could you fix this Zoom device under a camera." There is specific mention in the press release about an optional attachment that allows for standard attachment of the H6 under a camera so... that's taken care of.
Third: Lots of mention of no Phantom but since we don't have a full set of specs I have to assume they wouldn't degrade from the H4n. The H4n has 48/24V Phantom which is controlled in a menu NOT by a switch and should be same with the H6.
I can't believe the 20hour time they list for anything "real" but any improvement over the 1h40m I get out of the pair of AAs in the H4n when recording 2 channel 96k/24bit w/ 24V Phantom would be huge. If the 4 batteries at least double that my life would be a lot better. If the new device is also more efficient and I can get at least 8 hours / charge I'll love Zoom 4 eva!

I have a Lunatec V3 I use for an input to my laptop if recording to that. It is also better sounding than the H4n preamps BUT not enough to justify using it ahead of the H4n when it's my on-site recorder.
